suite. This reduces the number of failures from 9 to 7.
Both ConnectionTest and JBuilderTest did not create their own
tables, which caused these test cases to fail with "relation ...
does not exist". It appears these test cases relied on tables
created by the example code elsewhere in the source tree. I've
added the necessary "create table" and "drop table" statements
to the test cases, using the column definitions from the example
code.
While working on that I modified the helper method createTable
in JDBC2Tests.java to take a table parameter, rather than using
table names passed via the properties in build.xml. I'm not sure
what that was good for, and in fact, except for the default
table name "jdbctest", this functionality wasn't used at all.

discussion on pgsql-hackers (especially the frightening memory dump in

claims of the suitability of PQescapeString() for identifiers have
been removed.

table creation time. Big deal you say - but this patch is the basis of the
next thing which is adding PRIMARY KEYs after table creation time. (Which
is currently impossible without twiddling catalogs)
Rundown
-------
* I have made the makeObjectName function of analyze.c non-static, and
exported it in analyze.h
* I have included analyze.h and defrem.h into command.c, to support
makingObjectNames and creating indices
* I removed the 'case CONSTR_PRIMARY' clause so that it properly fails and
says you can't add primary keys, rather than just doing nothing and
reporting nothing!!!
* I have modified the docs.
Algorithm
---------
* If name specified is null, search for a new valid constraint name. I'm
not sure if I should "lock" my generated name somehow tho - should I open
the relation before doing this step?
* Open relation in access exclusive mode
* Check that the constraint does not already exist
* Define the new index
* Warn if they're doubling up on an existing index

Yes, it seems broken. It is a bug in libpgtcl. Are you running Tcl >= 8.3.2?
That's when the Tcl team changed the data structure for channel
callbacks. The change itself was designed to be backward compatible, but I
suspect a related change made the code more sensitive to errors in the
structure (NULL pointers where functions are required). Either that, or
nobody has tried to use libpgtcl with COPY in a long time.
First, I have to say I can't think of a good reason to use PostgreSQL's
COPY command from a Tcl application. I think it should only be used with
psql for importing data from another source into PostgreSQL, or for
exporting PostgreSQL data into another database (but why would anyone do
that?) If it was me, I would stick with SELECT and INSERT and be "SQL
Compliant".
OK, editorial is over. Try applying the patch below to fix
src/interfaces/libpgtcl/pgtclId.c
and let us know if it works. I did little testing on it, but my test did
segfault before and ran fine (copy in and copy out) after the patch. This
is for PostgreSQL-7.1.2 - since you are running older 7.0, I don't know if
this will work, but I suspect it will.
PS It's the absence of PgWatchProc which kills it. I didn't upgrade it
to the "V2" channel type structure, so it should be compatible with older
Tcl's. But aside from gets and puts, I doubt any other file operations
would work on the handle during a copy.

Actually, I think this change has a consequence for this method
in the same class:
public boolean isDefinitelyWritable(int column)
throws SQLException
{
return isWritable(column);
}
This is from the JDBC spec
(http://java.sun.com/j2se/1.3/docs/api/java/sql/ResultSetMetaData.html):
isReadOnly() - Indicates whether the designated column is
definitely not writable.
isWritable() - Indicates whether it is possible for a write on
the designated column to succeed.
isDefinitelyWritable() - Indicates whether a write on the
designated column will definitely succeed.
At this time we don't really implement the fine semantics of
these methods. I would suggest the following defaults:
isReadOnly() false
isWritable() true
isDefinitelyWritable() false
And that would mean that your patch is correct, but
isDefinitelyWritable() would need to be patched accordingly:
public boolean isDefinitelyWritable(int column)
throws SQLException
{
return false;
}
Again, both in jdbc1 and jdbc2.

The author probably intended:
public boolean isWritable(int column) throws SQLException
{
return !isReadOnly(column);
}
And if he would have coded it this way he wouldn't have made
this mistake :-)

Why exactly? In a way, true is just as incorrect as false, and
perhaps it should throw "not implemented". But I guess that
would be too non-backwardly-compatible.

Fixed.
I found new bug in command/variable.c in parse_client_encoding(), nobody
probably never see this error:
if (pg_set_client_encoding(encoding))
{
elog(ERROR, "Conversion between %s and %s is not supported",
value, GetDatabaseEncodingName());
}
because pg_set_client_encoding() returns -1 for error and 0 as true.
It's fixed too.
IMHO it can be apply.

See attached revised patch. (I'm sure the configure.in stuff can be done
right/better, I'm just not enough of a autoconf guru to know what to
change it to.)

flawed in the following ways:
1. Only returned columns that had a default value defined, rather than all
columns in a table
2. Used 2 * N + 1 queries to find out attributes, comments and typenames
for N columns.
By using some outer join syntax it is possible to retrieve all necessary
information in just one SQL statement. This means this version is only
suitable for PostgreSQL >= 7.1. Don't know whether that's a problem.
I've tested this function with current sources and 7.1.3 and patched both
jdbc1 and jdbc2. I haven't compiled nor tested the jdbc1 version though, as
I have no JDK 1.1 available.
Note the discussion in http://fts.postgresql.org/db/mw/msg.html?mid=1029626
regarding differences in obtaining comments on database object in 7.1 and
7.2. I was unable to use the following syntax (or similar ones):
select
...,
description
from
...
left outer join col_description(a.attrelid, a.attnum) description
order by
c.relname, a.attnum;
(the error was parse error at or near '(') so I had to paste the actual
code for the col_description function into the left outer join. Maybe
someone who is more knowledgable about outer joins might provide me with a
better SQL statement.

the JDBC driver.
I've done this by extracting it into a new method object called
QueryExecutor (should go into org/postgresql/core/) and then taking it
apart into different methods in that class.
A short summary:
* Extracted ExecSQL() from Connection into a method object called
QueryExecutor.
* Moved ReceiveFields() from Connection to QueryExecutor.
* Extracted parts of the original ExecSQL() method body into smaller
methods on QueryExecutor.
* Bug fix: The instance variable "pid" in Connection was used in two
places with different meaning. Both were probably in dead code, but it's
fixed anyway.

for the changed files and a few new files:
- test/jdbc2/BatchExecuteTest.java
- util/MessageTranslator.java
- jdbc2/PBatchUpdateException.java
As an aside, is this the best way to submit a patch consisting
of both changed and new files? Or is there a smarter cvs command
which gets them all in one patch file?
This patch fixes batch processing in the JDBC driver to be
JDBC-2 compliant. Specifically, the changes introduced by this
patch are:
1) Statement.executeBatch() no longer commits or rolls back a
transaction, as this is not prescribed by the JDBC spec. Its up
to the application to disable autocommit and to commit or
rollback the transaction. Where JDBC talks about "executing the
statements as a unit", it means executing the statements in one
round trip to the backend for better performance, it does not
mean executing the statements in a transaction.
2) Statement.executeBatch() now throws a BatchUpdateException()
as required by the JDBC spec. The significance of this is that
the receiver of the exception gets the updateCounts of the
commands that succeeded before the error occurred. In order for
the messages to be translatable, java.sql.BatchUpdateException
is extended by org.postgresql.jdbc2.PBatchUpdateException() and
the localization code is factored out from
org.postgresql.util.PSQLException to a separate singleton class
org.postgresql.util.MessageTranslator.
3) When there is no batch or there are 0 statements in the batch
when Statement.executeBatch() is called, do not throw an
SQLException, but silently do nothing and return an update count
array of length 0. The JDBC spec says "Throws an SQLException if
the driver does not support batch statements", which is clearly
not the case. See testExecuteEmptyBatch() in
BatchExecuteTest.java for an example. The message
postgresql.stat.batch.empty is removed from the language
specific properties files.
4) When Statement.executeBatch() is performed, reset the
statement's list of batch commands to empty. The JDBC spec isn't
100% clear about this. This behaviour is only documented in the
Java tutorial
(http://java.sun.com/docs/books/tutorial/jdbc/jdbc2dot0/batchupdates.html).
Note that the Oracle JDBC driver also resets the statement's
list in executeBatch(), and this seems the most reasonable
interpretation.
5) A new test case is added to the JDBC test suite which tests
various aspects of batch processing. See the new file
BatchExecuteTest.java.

I believe that the attached patch is the correct solution -- I apologize
for the gyrations. With the attached patch, Cygwin libpq++ builds
cleanly again. The root cause was that DLLIMPORT was defaulting to
__declspec(dllimport) since BUILDING_DLL was *not* defined when building
the libpq++ DLL.
Unfortunately, to test my patch requires changing the following makefile:
src/interfaces/libpq++/examples/Makefile
and the #includes in all of the *.cc to build against the source tree
instead of the following hardcoded installation directory structure:
/usr/local/pgsql
I was able to manually build
src/interfaces/libpq++/examples/testlibpq0.exe
against my Cygwin libpq++ without errors. However, I have not tried to
actually test testlibpq0.exe.
Is this sufficient? Or, do you want me to clean up libpq++/examples too?
(Or, is it silly to even ask? :,)) Let me know how you want to proceed and
I will submit a patch to pgsql-patches.

two additional files win32.mak and libpgtcl.def.
This patch allows to compile libpgtcl.dll on Windows
with tcl > 8.0. I've tested it on WinNT (VC6.0), SUSE Linux (7.0)
and Solaris 2.6 with tcl 8.3.3.

really played it totally safe in my last suggestion, the system table might
pick up the msg but not the netmsg.dll, so better try both.
I also added a hex printout of the "errno" appended to all messages, that's
nicer.
If anyone hate my coding style, or that i'm using goto constructs, just tell
me, and i'll rework it into a nested if () thing.
